Why do IG units have sealant leakage?

Sealant leakage is usually caused by incorrect sealant temperature or viscosity, poor spacer bending accuracy, glass size deviation, surface contamination, or unstable 2K sealing ratios.

How can I prevent sealant leakage in insulated glass units?

Maintain correct sealant temperature, ensure precise spacer bending, keep glass surfaces clean, use stable A/B sealant ratios, and consider using an automatic sealing robot for consistent quality.

Can equipment problems cause IG sealant leakage?

Yes. Butyl extruder temperature errors, 2K sealant mixing issues, worn nozzles, and inconsistent machine pressure can all lead to poor sealing performance and leakage.

Does manual sealing increase the risk of leakage?

Manual sealing often leads to uneven sealant lines and inconsistent corner filling. Using an automatic IG sealing robot significantly reduces leakage and improves product stability.

What is the best long-term solution for reducing IG sealant defects?

Investing in automated equipment—such as an IG sealing robot, automatic spacer bending machine, and calibrated 2K sealant pump—offers the most consistent and long-term solution to eliminate sealing problems.

I have now owned this butyl coating machine for 8 months. I use it on a daily basis and have made well over 2000 items, meaning the cost of produce the IGUs each is around 100 cents. How can that be a bad thing? I haven't upgraded or changed anything. I have upgraded my review to 5 stars, because even though there were some software issues in the beginning, there is literally no better machine for the money.

Great customer service, very responsive to emails, living-videos and helping sort out any equipment's issues. This type of insulating glass production line is well built and easy to use. Very easy to put together by after-service engineers. Took me about 3 hours to put together and another 30 minutes to figure out how to use the software. This price was good for a glass process beginner.

I researched many types/brands of insulating glass aluminum spacer strips bending machines for aluminum strips bending quartz countertops. Finally, I decided to give the LJZW2020 from LIJIANG Glass a try. After assembling and adjusting, I made my first strips cutting and bending with no issues. Good saw for industrial use, precision and stability are the best ways to cut strips with this automated machine.
